president obama's pick for defense secretary chuck hagel was on the hot seat today. the former nebraska senator defended his record at a confirmation hearing taking on issues that ranged from israel to iran to his support for a group that advocates nuclear weapons. hagel was challenged on the troop surge in iraq. >> i would like you to answer whether you were right or wrong and then you are free to elaborate. >> well, i'm not going to give you a yes or no answer on a lot of things today. >> let the record show refused to answer that question. i actually would like an answer yes or no. >> well, i think it's far more complicated than yes or no. as i've already said, my answer is i'll defer that judgment to history. i'm fully committed to the president's goal of preventing iran from obtaining a nuclear weapon. as i have been on record on that issue, as i've said in the past many times, all options must be on the table to achieve that goal. >> despite tough criticism from republicans hagel is expected to be confirmed as the next defense secretary. >>> also up on the hill
